About Observable
Observable is a data analysis and visualisation platform from the team behind the D3 charting library. Its best-known product is the Observable notebook, where JavaScript, SQL and Markdown cells react to each other and charts update as data changes, which makes it popular for interactive graphics and data journalism. The company also makes Observable Canvases for exploring data visually, Observable Plot, a charting library, and Observable Framework, an open-source static site generator for dashboards and reports that can load data with any language on the back end. Framework and Plot are free under the ISC licence on GitHub; the hosted platform has a free tier for individuals and paid plans for teams that need private sharing and more control. It suits analysts, designers and developers who think in charts and want to publish them, while people who mainly work in Python may find Jupyter-style notebooks more familiar.
Best for: Analysts and developers building interactive JavaScript charts and dashboards to share.
Pros and cons
What works
- Reactive notebooks where charts update as soon as inputs change
- Made by the D3 team, with strong charting tools built in
- Open-source Framework and Plot can be used without the hosted service
Why people leave
- Built around JavaScript, which is less familiar to Python-first data scientists
- Private team sharing needs a paid plan
- Several separate products can make the offering confusing at first
